Description

Overview 18mm Threaded Bung with Plug 304 Stainless Steel Not compatible with OEM O2 Sensors Install on Stainless or Mild Steel Exhausts This kit includes a 304 stainless steel bung and plug to allow the use of an aftermarket oxygen sensor. If your Brocks Performance exhaust system has an O2 sensor bung pre-installed, the plug can be used to block off the existing bung. If your exhaust system does not have a bung pre-installed, it will be necessary for a qualified welder to install the supplied bung (MIG process suggested) onto your exhaust system. Bung and plug are both industry standard 18mm thread used in most aftermarket 5 wire or Bosch style applications and are not compatible with most OEM (stock) O2 sensors, which are typically 12mm threads. Bung and plug sold as a kit.
